Symbian handsets have many hidden talents and functions. One of which is the ”remote phone locking” function. This function allows to lock your S60 device like the Nokia N97 via a text message from everywhere.
If, for example, somebody had stolen your precious Nokia N97 with really important and private data you can simply write a text message to your phone number and immediately your N97 is locked. However, first you need to activate this function.Therefore go into the menu and than choose ‘settings‘, ‘phone‘, ‘Phone mgmt‘, ‘Security settings‘, ‘Phone and Sim card‘ and finally ‘Remote phone locking‘. Once you enable it you have to define a message like e.g. ”nokian97” and afterwards verify it again. Now you have activated this function.
